So what's the actual syntax for putting commands in server.cfg on a dedicated server?  I've tried a number of things and none work.  In doing a Google search, I see a lot of variations but nothing definitive.  Regardless of the command, is it:

server.maxplayers 25
server.maxplayers "25"
+server.maxplayers 25
+server.maxplayers "25"

or something else entirely different.

One command per line as you’d enter them in the server console. All Rust does is run each line as a command.
